Window wrap

ABSTRACT

A window wrap used to accommodate and protect various thicknesses of drywall around a rough window frame, which forms a window frame with perfectly square corners. The window wrap has a jamb/sill extension and a wall extension, each extending perpendicular to each other. The wall extension has a front surface, a rear surface, and a distal surface extending between the front and rear surfaces, and is adjustable to fit various thicknesses of drywall panel. A layer of primer or adhesive laminate is applied to the front surface of each extension so that paint can bond to the front surface. The jamb/sill extension of the window wrap may also be made similar to the wall extension and used to form any depth of jamb/sill.

FIELD OF THE INVENTION

[0001] The invention relates generally to window wraps, and, moreparticularly, to a window wrap that may be used to finish the drywalledges around windows.

BACKGROUND OF THE INVENTION

[0002] A window frame typically consists of side jambs and a head andbottom sill, formed in a rectangular shape. When a building is beingconstructed, a rough window frame is constructed, providing a space fora window through the wall. The rough frame may be constructed of avariety of materials, depending on the construction of the wall in whichthe window will sit, however typically the rough frame is constructedwith 2×4 or 2×6 studs. Drywall may then be placed over the framingsurface of the wall, and around the rough window frame opening. Thedrywall around the rough window frame is then either finished by formingcorners with drywall panels used to form the jambs and sills of thefinished frame, using any of the conventional means for finishingdrywall corners, or a window wrap is constructed out of wood or othermaterials, to provide the finished frame and cover the unfinished edgesof the drywall around the window frame.

[0003] These conventional methods of constructing a finished windowframe is time consuming, and to be done properly, requires the skills ofan experienced craftsman.

[0004] Drywall panels are widely used in the construction industry forforming the interior walls and ceilings of rooms. Drywall panels aremade of a gypsum or reinforced gypsum core covered with paper. Drywallpanels have the advantages of being easy to cut to desired sizes and toattach to assorted types of framing. However, it is very difficult tocut drywall panels so that the edges are perfectly straight and smoothand can meet to form a perfectly straight corner, which is aestheticallyto be desired. In addition, when the drywall panels are cut to thedesired sizes, the edges of the panels are left exposed. This exposedgypsum core is soft and tends to crumble unless the severed edges aresomehow protected. This is especially important at outside wall corners.

[0005] When window frames are built of framing materials such as wood,the inside and outside corners thereby formed are seldom perfectlystraight. Small variations in the sizes of the wood-framing members,warping of the wood, and inconsistent building practices lead toimperfectly straight corners where walls and window frames meet. Whendrywall panels are then attached to the crooked framing materials, theirintersections will also be crooked.

[0006] An assortment of devices have been used to provide a smooth anddurable finish for the intersections where two pieces of drywall abut toform an inside or outside corner, such as are present in finished windowframes. Among the conventional devices used are drywall tape and metalcorner beads. Conventional drywall tape is provided in narrow, elongatedribbons or strips of porous paper wound into rolls. The paper issometimes perforated to increase moisture penetration and to prevent airbubbles from being entrapped behind the tape. The drywall tape is firstapplied to joints and edges of abutting drywall panels and is thencovered with wet plaster, sometimes called “mud”. The plaster isfeathered and smoothed along the edges of the tape to conceal thedemarcations between the tape edges and the drywall panels to which thetape is applied. When the wet plaster has dried, the tape and drywallcan be painted or otherwise covered with a suitable wall covering.

[0007] A great deal of skill is needed to apply the plaster to bothsides of an inside corner such that a perfectly straight intersection isachieved. Also, to correct the crookedness resulting from the warpedframing members and inconsistent building practices described aboveoften several coats of plaster must be applied, with an entire day ofdrying time needed between each coat. Even then, a perfectly straightcorner seldom results. It is also likely that, unless in the most highlyskilled hands, the plaster trowel will mar the first side of the plasterwhile the second side is being applied. Once the plaster has beenapplied and dried, it must be sanded to an appropriate finish to providea surface suitable for the application of paint or wallpaper.

[0008] Because drywall tape is formed of paper, it is quite flexible andwill conform to various surface configurations of the edges ofintersecting panels of drywall. When conventional drywall tape is usedat the outside corners of walls, the flexibility of the tape oftenresults in a corner demarcation that is irregular, since the tapeconforms to irregularities in the exposed, severed edges of the drywallpanels. The tape is also fragile and does not stand up well to theconstant physical abuse suffered by outside corners. As a consequence,conventional drywall tape cannot be used at exposed outside corners.

[0009] To finish outside corners in building construction, therefore,metal corner beads are often used. Conventional metal beads areconfigured in an L-shaped or angle-shaped cross section and aretypically fabricated from elongated perforated strips of metal, such asgalvanized steel, permanently deformed with a lengthwise 90-degree bendto form elongated angles. The metal beading is typically positioned atthe intersections of adjacent drywall panels that meet at right anglesto form an outside corner within a room. The sections of metal beadingare nailed in place through the drywall panels to wooden supportingstructural members located behind the drywall panels. Wet plaster isthen smoothed into place to cover the metal flanges or leg members ofthe metal beading, and the edges of the plaster are smoothed andfeathered to attempt to conceal the metal edges.

[0010] While the rigidity of the metal beading does allow an outsidecorner of an inside building wall to be finished with a sharp, straightedge, which is aesthetically pleasing, the use of metal beading involvessome significant problems. Over time, the metal corner bead will rust,thereby producing rust stains that are clearly visible on the surfacesof the walls at the corner. It is not always possible to completelycover the edges of the metal flanges or the nail heads used to attachthe metal corner bead to the drywall panel, detracting from the desiredsmooth appearance of the wall. Cracks often develop in the overlyingplaster at the outer edges of the flanges. To prevent this fromhappening, often two or three coats of plaster are applied, with priorcoats allowed to dry and harden, which may take as long as 24 hours,before a subsequent coat is applied. When the corners are crooked orjagged due to problems with the underlying framing, metal beads do notcover enough surface area or have enough flexibility to correct theinequalities that exist. Another problem is inherent in the fact thatthe malleable metal from which the metal beads are made has a very poormemory and is subject to being dented or wrinkled, after which it isdifficult to straighten it to produce a smooth finish. Because of therough handling to which most of the material at a work site issubjected, it is not uncommon for the strips to be wrinkled, dented, andperhaps twisted, thus rendering them either unusable, or usable only toproduce an inferior end result. In addition, the metal strips are usedin large quantities in construction and can add up to considerable cost.

[0011] Furthermore, when drywall corners are used to finish the windowframe, the resulting frame is not very insulated. This type of frame isalso not very strong and cracks often times develop at the corners ofthe window frame. Outside air leakage will then also occur.

[0012] If a conventional window wrap is used, the resulting frame isstronger and may be more insulated, however, its use requires extratime, material and expense to install. Such conventional window wrapsare also prone to outside air leakage.

[0013] Therefore, a need exists for a window wrap that protects theedges of the drywall used around the window, provides perfectly straightcorners for the finished window frame, is strong, insulated, eliminatesoutside air leakage around the window frame, and is easy and economicalto use.

[0014] None of the described conventional ways of finishing a windowframe fulfills these needs.

[0015] The window wrap described herein is able to fulfill all thesebefore described needs. The window wrap has perfectly formed corners andmay be used for any depth jamb/sill. The window wrap covers and protectsthe exposed edges of drywall around the inside edge of he window frame,and is adjustable to fit various thicknesses of drywall panels. Thewindow wrap may be insulated and may be sealed to prevent outside airleaks. Finally, the window wrap may be economically manufactured due toits simplified cross-sectional shape.

SUMMARY OF THE INVENTION

[0016] A window wrap used to accommodate and protect various thicknessesof drywall around a rough window frame, which forms a window frame withperfectly square comers. The window wrap has a jamb/sill extension and awall extension, each extending perpendicular to each other. The wallextension has a front surface, a rear surface, and a distal surfaceextending between the front and rear surfaces, and is adjustable to fitvarious thicknesses of drywall panel. A layer of primer or adhesivelaminate is applied to the front surface of each extension so that paintcan bond to the front surface. The jamb/sill extension of the windowwrap may also be made similar to the wall extension and used to form anydepth of jamb/sill.

DETAILED DESCRIPTION

[0037] Drywall panels are conventionally supplied in predeterminedwidths, for example ⅜ inch, ½ inch, and ⅝ inch widths, etc., and notmeant to be inclusive. The window wrap of the present invention is ableto conform to any width of drywall panel used.

[0038] The window wrap of the present invention is preferably fabricatedusing drywall corner finishing device components which are the subjectof a previous but co-pending patent application, application Ser. No.09/888,011. Therefore, the drywall corner finishing device componentswill be described first, followed by a description of the window wrapconstructed using the drywall corner finishing device components.

[0039] Turning to FIGS. 1 and 1a, the left 102 and right 104 wings ofthe drywall corner finishing device component are attached to a flexiblecenter joint 100 and extend outwardly therefrom to a distal edge 110. InFIG. 1a, the wings 102, 104 have a front surface 106 and a rear surface108. The front surface 106 and rear surface 108 extend outwardly beyondthe outer strut 110 of the wings 102, 104. When the drywall cornerfinishing device covers either an inside corner or an outside corner,the rear surface 108 of the device is juxtaposed to the framing of aninterior wall while the front surface 106 faces out into the room,contiguous with the surface of the drywall panels forming the wall. Inthe embodiment shown in FIG. 1, wing 104 only has a front surface 106.The front surface 106 may be covered with a layer of primer 300 as shownin FIG. 3 so that any paint or wall covering that is eventually used todecorate the wall will adhere easily. Alternatively, the front surface106 may have an adhesive laminate 400 attached to it as shown in FIG. 4.

[0040] In the preferred embodiment of the drywall corner finishingdevice, a laminate 400 is used on the front surface 106. For bestresults the laminate should have extensible or flexible properties to itso that the laminate does not crack when the device is bent at theflexible joint, but otherwise have surface characteristics as similar tothose of drywall panels. Through extensive testing, best results werehad using a paper laminate manufactured by Fibermark of Fitchburg,Mass., and sold under product number X41693. It is understood thatdisclosure of this particular laminate does not limit the invention touse of only this laminate nor exclude the use of other laminates whichare also suitable for use with the device.

[0041] In the preferred embodiment, the paper laminate is affixed to thedevice by a pressure sensitive adhesive, which remains pliable afterapplication and during normal operating conditions of the device.Through extensive testing, best results were had using an adhesivemanufactured by Worthern Industries of Nashua, N.H., and sold underproduct number Nylco E-68. This adhesive provides a fusion level bondbetween the device and the laminate, which greatly reduces the tendencyof the laminate to separate from the device. Other suitable adhesivesinclude those which do not harden nor negate the extensible propertiesof the applied paper laminate.

[0042] The device itself may be extruded using various materials. In thepreferred embodiment of the invention, a PVC plastic is used,manufactured by Veka, Inc. of Fombell, Pa., and sold under productnumber X-15. It is understood that disclosure of this particularmaterial does not limit the invention to use of only this material norexclude the use of other materials which are also suitable for use withthe device.

[0043] The structure of the drywall corner finishing device component ismore clearly seen in FIG. 2. The flexible center joint 100 preferablyextends from the front surface of each wing to the other and is eithertapered or has parallel walls, but it is to be expressly understood thatany joint shape, such as actuate, V-shaped, U-shaped, C-shaped, etc. canbe used that allows the device to bend through a variety of angles atthe center joint 100. The center joint 100 extends along an axis thatextends linearly to form a corner or edge.

[0044] The tapered joint 101 embodiment of the flexible joint has afront surface which extends parallel to the front surface 106 of thedevice. The rear surface of the tapered joint 101 tapers inwardly fromthe two wings, toward the front surface. This allows for a sharp, cleancorner to form along the front surface of the tapered joint 101 here itis the thinnest, when the device is bent along the joint, as can be moreclearly seen in FIG. 6.

[0045] The tapered joint 101 embodiment of the flexible joint may beused to form both inside and outside corners.

[0046] A number of struts 206 separate the rear surface 108 of each wing102, 104 from the front surface 106 of each wing 102, 104. In theembodiments shown in FIGS. 1a, 1 b and 2, the pattern of struts 206provides stability to the structure of the corner device and also allowsthe device to be folded around outside corners, as discussed in moredetail below. It will be obvious to one skilled in the art that thepattern of struts 206 shown in FIGS. 1 and 2 is not the only patternthat will provide these features of stability and folding and that otherpatterns would be suitable and are to be included in the presentinvention.

[0047] The edge 202 of the rear surface 108 extends beyond the edge 200of the front surface 106. The outer portion 204 of the front surface 106tapers slightly toward the rear surface 108 so that, as discussed inmore detail below, the edge of a drywall panel can be placed in thespace 114 between the front surface 106 and the rear surface 108 suchthat the edge 202 of the rear surface 108 and the edge 200 of the frontsurface 106 are in close opposition to the drywall panel.

[0048] A flexible flange joint 113 is located at the intersection of therear surface 108 and the outer edge 110. The rear surface 108 may thenbe bent at the flexible flange joint 113 thereby allowing the rearsurface flange 112 to pivot about the flexible flange joint 113 toadjust the space 114 between the front surface 106 and rear surface 108to fit various thickness drywall panels.

[0049] It is to be understood that types of flexible flange joints 113other than that illustrated in FIGS. 1-13 can be used in the presentinvention and that the present invention includes all types and designsof joints that provide the above-described bending and pivoting.

[0050] In the preferred embodiment of the device, the front surface 106and the rear surface 108 taper slightly towards each other, as theyextend towards the distal ends of each wing 102, 104. This tapering ofthe wings 102, 104 helps to facilitate a smooth transition from thesurfaces of the device and the surfaces of the inserted drywall panels.

[0051]FIG. 5 illustrates the drywall corner finishing device bent at thecenter joint 100, at a 90°angle, as shown by arrow 500, to form anoutside corner. Four drywall corner finishing devices are needed, eachformed in a 90° outside corner, to be used as the jamb and sill portionsof the window wrap. The four portions of the window wrap consist of twoside jamb portions, a head sill portion, and a bottom sill portion.

[0052] As FIG. 7 shows, the ends of each portion are cut at an angle toform a 90°mitered-joint between the ends of each joined portion. In thisconfiguration, the wings of the drywall corner finishing device now forma wall extension 302 and a jamb/sill extension 304.

[0053] FIGS. 8-12 show the four jamb/sill portions assembled together toform the window wrap. The portions are joined at each miter-joint 306.While the jamb sill portions may be joined together in any fashion, thepreferred connection is with a mitered-joint. The mitered-joint may befastened together by a fastener or adhesive. However, the preferredmeans of joining each miter-jointed end is to fuse or weld each end toeach other. By doing this, an air and water tight seal is formed betweeneach adjacent portion. The wall extensions 302 of each portion allextend outwardly from the center joint and lie in the same plane. Thejamb/sill extensions 304 of each portion now all extend rearward fromthe center joint, each extension perpendicular to the adjacentextension.

[0054] Thus, the above-described window wrap may be manufactured toaccommodate any size window frame simply by varying the lengths of jambportions and sill portions joined together. The jamb/sill extensions mayalso be varied to accommodate any desired jamb/sill depth. If thedesired jamb/sill depth is shallower than the length of the jamb/sillextension, the extension may be cut to the proper depth. However, if thedesired jamb/sill depth is deeper than the length of the jamb/sillextension, a piece of drywall may be inserted into jamb/sill extensionto provide the desired depth.

[0055] The window wrap may then be inserted, as a unit, directly intothe rough window frame. It is preferred that an adhesive be used betweenthe rear surface 202 of the wall extensions 302 and the rough frame.However, a trim channel or caulk my also be used between the window wrapand the rough window frame. The use of adhesive allows for settlement ofthe window wrap, reduces the chance of cracking at the corners of thewindow wrap, and provides an almost airtight seal between the windowwrap and the frame. The drywall panels on the framing wall around thewindow frame may then be inserted into the space 114 of the wallextension 302 of the window wrap.

[0056] As an example, in FIG. 13, the extension of the window wrap isattached to the wall framing 800 by use of nails 806. The window wrappreferably is made of plastic soft enough to permit the nails 806 to bedriven through the flange 112 of the rear surface 108 without the needfor pre-formed holes. It is to be expressly understood that othermethods such as the use of screws, bolts, adhesive, etc. will be equallyefficacious in attaching the window wrap to the supporting members ofthe framing. The attachment location of the window wrap and thepositions of the nails 806 can be varied to enable the window wrap tocorrect inequalities that may exist within the framing and from oneframing member 800 to the next. If necessary, shims may be placed behindthe window wrap before it is attached by nails 806 or affixed by anadhesive. The edges of the drywall panels 804 are inserted into thespaces 114 between the front surface 106 and rear surface 108, such thatthe edges of the drywall panels 804 abut the outer strut 110 of thewings 102, 104. It can be seen in FIG. 13 that the spaces 114 betweenthe front surface 106 and rear surface 108 are just large enough toaccommodate the drywall panels 804 and that the front surface 106 andrear surface 108 are closely juxtaposed to the drywall panels 804. Thedrywall panels 804 thus hide the nails 806. The drywall panels 804 areattached to the framing 800 in the usual fashion.

[0057] As FIG. 13 shows, plaster 1300 is then applied to the tapereddistal portion 204 of the front surface 106 and the tapered edge of thedrywall panel 804 to hide the edge 200 and provide a smooth, levelsurface. Because plaster 1300 is applied only to the tapered portion 204of the finishing device, difficulties inherent in plastering withincorners are avoided. Such difficulties include, among others, thedifficulty in maneuvering a plaster trowel within a corner, the skillneed to produce a perfectly straight edge where the two sides of thecorner meet, and the need for several layers of plaster 1300 tocompletely hide the joint between the window wrap and the drywall or tocorrect the inequalities resulting from mis-sized, mis-placed, or warpedframing members, with each layer requiring considerable time to dry.Once plaster 1300 has been applied, the surface of the wall or sill/jambcan be finished by painting, wallpapering, or any other method desired.The primer 300 bonded to the front surface 106 enables paint or otherwall coverings to adhere to the front surface 106 of the finishingdevice. In another embodiment, a laminate 400 can be adhesively affixedto the front surface 106 to provide a surface for subsequent painting.

[0058] Plaster alternatives may also be used to hide the edge 200.Plaster alternatives include, but are not limited to stucco, stuccoplasters, synthetic stucco and cement siding products.

[0059] Alternatively, the window wrap may be installed without applyingplaster between the edges of the window wrap and the drywall, to hidethe window wrap edges. The window wrap may then be painted or covered inany way desired, providing a visual border around the border. Anotheralternative is to hide the window wrap by placing molding over the edgesof the window wrap and drywall.

[0060]FIG. 14(a) illustrates the wall or jamb/sill extension in aresting position. When ½″ drywall panel 1500 is inserted into space 114between the edges 200, 202 as shown in FIG. 14(b), the drywall panel1500 is held against the rear surface flange by edge 200 as shown inFIG. 14(c).

[0061]FIG. 15(a) illustrates ⅝″ drywall panel 1600 inserted into space114 between the edges 200, 202. With the greater thickness drywall panel1600, rear surface flange 112 pivots at flexible flange joint 113, awayfrom the front surface 106. Front surface 106 remains relativelystraight due to outer strut 110, which extends from the front surface106 of the extension away from the end of each wing, to the rearsurface. Another consideration which helps to allow the front surface106 to remain relatively straight while the rear surface flange 112pivots, is that the wall thickness of the rear surface 108 is slightlythinner than that of the front surface 106. This effect could also befacilitated in other ways such as reducing the wall thickness of therear surface 108 where it intersects the outer strut 110 at the flexibleflange joint 113, thereby weakening the immediate area, allowing theflange joint 113 to pivot more easily.

[0062]FIG. 15(b) illustrates rear surface flange 112 held in placeadjacent drywall panel 1600 once the extension and drywall panel 1600are installed, as further shown in FIG. 16.

[0063] Best results when using the device were found when an adhesivewas used to affix the inside surface of space 114 of an extension withthe drywall. Preferably a fusion bond adhesive is used. Two adhesiveswhich were found to be suitable for this application are product numberPL Premium manufactured by OSI Sealants of Mentor, Ohio and productnumber F2100 in combination with product number F2100A, manufactured byITW Foam Seal of Oxford, Mich. It is understood that disclosure of theseparticular adhesives does not limit the invention to use of only theseadhesives nor exclude the use of other adhesives which are also suitablefor use with the device.

[0064]FIG. 16 illustrates how the extension of the window wrap isinstalled with a ⅝″ panel 1600. A block 1700 may be used to keep thedevice and the drywall panel 1600 parallel with the framing surfacewhich the drywall panel 1600 is attached. The block 1700 is affixed tothe rear surface 108 of the extension. The window wrap and drywall panel1600 are affixed to the framing surface by nails 1702 or some otherfastening device. When the nails 1702 are fastened into the framingsurface, the rear surface flange 112 is sandwiched between and adjacentto the framing surface and the drywall panel 1600. Thus, this windowwrap can be used for drywall panels that are thicker than the thicknessof the device.

[0065] The window wrap of the present invention may be modified inseveral ways. First, the window wrap may be constructed of a solidmaterial or a material other than plastic. Second, the drywall cornerfinishing device component may be extruded with a 90° bend at the centerbetween the two wings, the joint between the two being rigid. While thiswould save the step of bending the device between the extrusion and theangled-cut steps, it is easier to store and transport the device, beforethe jamb/sill portions are connected together when the device is flat.Third, if added insulation in the window wrap is desired, insulation maybe placed between the struts before each portion is joined together.Fourth, each of the outer portions of front and rear surfaces of eachextension, which are adjacent the outer edges, and are free ofreinforcing structure, may be excluded. Fifth, each of the jamb and sillportions may be connected together other than by a mitered joint orother than by fusing or welding the portions together. Sixth, each ofthe wall or jamb/sill extensions may be constructing using only a singlesurface. Lastly, the jamb and sill portions may be connected together atangles other than 90° to each other, allowing for use with differentshaped window frames.
